What is DSP and how does to apply to Composer-based hardware?
Advanced Digital Signal Processing is at the core of our Composer-based hardware. Our solutions simply design and deliver superb fidelity, adding value for designers, integrators, and end users.
Where can I find a Quick Start Guide on the BreakIn 12?
Can I talk to Composer-based DSPs using HyperTerminal?
If the unit has RS-232 control, yes. HyperTerminal can be used to simulate an external controller.
Default settings:
Baud: 38400
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
How many SymNet units can I connect together with SymLink?
There can be a maximum of 16 SymNet hardware units in a SymLink ring. This includes the 8×8 DSP, 8in DSP, 8out DSP, CobraLink, BreakIn12, Breakout12, and DigIO 12×12 DSP.
Will phantom power damage my non-condenser microphones?
Generally no, some older ribbon microphones are somewhat susceptible, but it’s always a safe bet to disable phantom power when not needed.
What is SymVue Discovery?
SymNet Designer 9.1+ software features a discovery app that gives users immediate visibility of IP equipped devices on your network. Learn more in this Tech Tip:
Where can I find an owner's manual for my Symetrix product?
All technical and operational instructions and documentation for current Symetrix products are contained within the Help menu of the Designer and/or Composer software. Simply click on the question-mark icon on the toolbar in Designer/Composer and search your topic.
Download the latest version of Designer or Composer at www.symetrix.co.

Will phantom power damage my non-condenser microphones?
Generally no, some older ribbon microphones are somewhat susceptible, but it’s always a safe bet to disable phantom power when not needed.
How much latency is there in a SymNet SymLink system?
This question has a three part answer since the digital signal path through a SymNet system has three different major components.
Converter delay: Approximately 850 microseconds for the AD, and 624 microseconds for the DA.
One DSP core: Maximum delay through any given 8×8 DSP core is approximately 240 microseconds, though typically it will be much lower. The max delay through the DSP core of an 8in or 8out is 120 microseconds.
SymLink: Approximately 80 microseconds for an audio signal to travel, via SymLink, from the DSP core of one 8×8 to the unit immediately downstream. If there are any units in between, add an additional 80 microseconds for each SymNet DSP, 20 microseconds for each CobraLink and 20 microseconds for each BreakIn12 and BreakOut12.
In summary: The typical delay for a signal that goes into an analog input on an 8×8, and exits from an analog output on the same 8×8 is usually around 1.5 milliseconds.
Where can I find the External Control Protocol for SymNet SymLink, Express, and Solus units?
The External Control Protocol for SymNet units can be found below. This document covers all third-party control for SymNet units including both RS-232 and UDP (IP).
Where can I find a Data Sheet on the BreakIn 12?
Where can I find specifications or a Data Sheet for the CobraNet and SymLink SymNet line?
A Full Line SymNet Product Catalog complete with specifications can be found below. Additional installation information and/or specifications may be found in each product’s Quick Start Guide (if applicable).
Can I plug a microphone directly into a SymNet 8x8DSP, 8 In, or BreakIn 12?
Yes. All SymNet 8×8 DSP, 8 In and BreakIn 12 units’ with analog audio inputs are equipped with software controlled mic/line inputs. In the 8×8 and 8in, digitally controlled precision analog attenuators are part of the analog input stages. Adjustments made to the input gain block in SymNet Designer actually trim the level of analog signal being sent to the A/D converter – allowing you to maximize the dynamic range performance of the SymNet hardware. On the BreakIn12, software controls the coarse gain levels of the mic preamp and fine trim is done with DSP modules in SymNet Designer.
What is Phantom Power?
Phantom power derives its name from its invisibility to audio signals, even though the microphone cable carries both phantom power (as direct current) and audio signals (as alternating current). Specifically, the term phantom power means a positive DC voltage sent to the microphone on both audio leads, through current-limiting resistors which also serve to isolate the audio leads from one another. The front panel phantom power button applies phantom power via pins 2 and 3 of the mic input XLR connectors.
How do I control SymNet over the Internet?
In SymNet Designer 9.1 and later it is possible to control multiple IP equipped SymNet units over the Internet (wide area network, or WAN). Multiple devices can be accessed from a single external IP address. This is accomplished by using unique port numbers for each device.
To configure WAN communication for your system open the Help files contained within the SymNet Designer software and perform a search for “WAN” or see the chapter entitled “Menu Bar – File – Preferences.”
Can you acccess multiple SymNet units over the Internet?
Did you know SymNet Designer 9.1 or later can access multiple SymNet units over the Internet? Find out more in this Tech Tip:
What is the maximum voltage recommended for the analog control inputs on a SymNet device?
The input stage of an analog control input of a SymNet device will clamp on an input exceeding +5.5V. Anything above +5.5V will draw excessive current (the amount depending on the output resistance of the device supplying the current) and could possibly damage the input stage. Keep analog control input current to below +5.5V.
Where can I find an Ethernet application with IP capable Symetrix products?
SymNet Remote Terminal is a UDP terminal test application for testing Ethernet-based control for Symetrix products.
